JMNT(i)
21 You folks are unable to continue to drink (or: You can not habitually drink) [the] cup of the Lord (or: the Owner's cup; or: = the cup pertaining to Christ; or: [Yahweh's] cup; cf John 18:11) and a cup of demons (or: a cup pertaining to animistic influences [possibly: = evil attitudes; deranged mental conditions; evil spirits]); you are unable to continue to (or: to habitually) hold a share with and co-partake of [the] Lord's [= Christ's or Yahweh's] table and also a table of demons (pertaining to or having its source in animistic influences [possibly: = evil attitudes or qualities]). [note: Mal. 1:7 refers to the altar of burnt-offering as “the table of the Lord;” Isa. 65:11, Jer. 7:18 and Ezk. 1618; 23:41 use the term “table” with reference to pagan idol-feasts; Paul may be using the terms “cup” and “table” figuratively, and not referring to specific ceremonies]
22 Or are we proceeding to cause the Lord's emotions to boil over the side (constantly inciting the Lord [= Christ, or Yahweh; cf Deut. 32:21, LXX] to jealous indignation)? We are not stronger than He!
